Maybe you could use "rsync", which does exactly that - transfer only a file which has changed.
I hope this helps.

LEARN ABOUT PHP
ftp_nb_put
FTP_NB_PUT(3) 1 FTP_NB_PUT(3)
ftp_nb_put - Stores a file on the FTP server (non-blocking)
SYNOPSIS
int ftp_nb_put (resource $ftp_stream, string $remote_file, string $local_file, int $mode, [int $startpos])
DESCRIPTION
ftp_nb_put(3) stores a local file on the FTP server.
The difference between this function and the ftp_put(3) is that this function uploads the file asynchronously, so your program can perform
other operations while the file is being uploaded.
PARAMETERS
o $ftp_stream
- The link identifier of the FTP connection.
o $remote_file
- The remote file path.
o $local_file
- The local file path.
o $mode
- The transfer mode. Must be either FTP_ASCII or FTP_BINARY.
o $startpos
-The position in the remote file to start uploading to.
RETURN VALUES
Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA.
EXAMPLES
Example #1
ftp_nb_put(3) example
<?php
// Initiate the Upload
$ret = ftp_nb_put($my_connection, "test.remote", "test.local", FTP_BINARY);
while ($ret == FTP_MOREDATA) {
// Do whatever you want
echo ".";
// Continue uploading...
$ret = ftp_nb_continue($my_connection);
}
if ($ret != FTP_FINISHED) {
echo "There was an error uploading the file...";
exit(1);
}
?>
Example #2
Resuming an upload with ftp_nb_put(3)
<?php
// Initiate
$ret = ftp_nb_put($my_connection, "test.remote", "test.local",
FTP_BINARY, ftp_size("test.remote"));
// OR: $ret = ftp_nb_put($my_connection, "test.remote", "test.local",
// FTP_BINARY, FTP_AUTORESUME);
while ($ret == FTP_MOREDATA) {
// Do whatever you want
echo ".";
// Continue uploading...
$ret = ftp_nb_continue($my_connection);
}
if ($ret != FTP_FINISHED) {
echo "There was an error uploading the file...";
exit(1);
}
?>
